You can send texts thru the Watch but there is no keyboard. You have to either use one of the preset replies or dictate one. It can be a little awkward depending where you are (ie - won't work well in a noisy environment and people might look at you funny in a quiet environment).

At first the 38 seemed a little small but it's growing on me. I come from a much bigger faced watch but when I was looking at pictures before my purchase I was not happy the way the 42 looked on people's wrist. I know mileage may vary but the nearest Apple Store is almost four hours away so I went with what I had to go on. That being said...I love it can't wait to buy more bands for it!
